Title: Character recognition system
Inventor: TACHIKAWA MICHIYOSHI
IPC: G06K9/46
Filed: 1986-11-20
Abstract: PURPOSE:To improve the efficiency of the character recognition processing without degrading the recognition rate by sorting input characters coarsely by using the feature amounts of character patterns to decrease the number of kinds of characters that may be candidates. CONSTITUTION:An image data inputted from a scanner 1 is subjected to a line segmenting part 2, a character segmenting part 4, and a pre-processing part 6, and temporarily stored in a character image memory 5. A coarse sorting feature/fine feature extraction part 7 extracts a coarse sorting feature amount and a fine feature amount from amont the pre-processed character patterns in the character image memory 5, and these data are temporarily stored in a feature amount memory 8. A matching part 10 executes the fine matching between the coarse sorts of input characters generated by using coarse sorting feature amounts extracted from input character patterns and a dictionary as well as between an input character generated by using fine feature amount related to the kinds of characters decreased by the coarse sorting and the dictionary.

Title: Manufacture of compound superconducting wire
Inventor: MATSUMOTO KANAME
IPC: B22F9/04
Filed: 1991-09-26
Abstract: PURPOSE:To provide a method for effectively manufacturing a compound superconducting wire having excellent superconductive characteristic. CONSTITUTION:Powders of metal A and metal B forming A51 type compound superconductor are mixed together in a determined ratio to form a mixed powder. The mixed powder is subjected to mechanical ironing treatment to form an alloy powder. The alloy powder is charged in a metallic pipe having excellent workability to form a composite billet. The composite billet is drawn into a composite wire rod having a desired form, and the composite wire rod is subjected to a determined heating treatment. Since the metallic pipe having excellent workability is used in the outer circumference of the composite billet, the composite billet can be drawn without intermediate annealing. Further, since the alloy power obtained by mechanically ironing the mixed power of the metal A and metal B mixed in the determined ratio is used as the raw material for compound superconductor, a compound superconductor excellent in superconductive characteristic can be provided by heating treatment in a short time.

Title: Semiconductor device and its manufacture
Inventor: WATABE KIYOTO
IPC: H01L29/739
Filed: 1994-11-11
Abstract: PURPOSE: To reduce ON-voltage by forming a gate electrode in such a manner that the surface area of a region covering a first base layer becomes larger than the surface area of a region covering a second base layer. CONSTITUTION: Emitter side of an IGBT corresponds to a cathode of a cathode- short-circuit diode, and the collector side of the IGBT corresponds to an anode of the cathode-short-circuit diode. Forward voltage of a cathode-short-circuit diode becomes lower as the percentage of cathode-short-circuit (Wn)/(Wn+Wp) increases. Where, Wn is the width of n-type diffusion layer, and Wp is the width of p-type diffusion layer. Therefore, the percentage of the cathode short- circuit can be increased by increasing the width (Wn) of an overlap region between a gate electrode 14 and n-type base layer 1. By doing this, ON voltage can be made lower than the conventional one.
